Slow compilation time on linux?
I have a fairly large C++ template application that include a large number of header files from the
itk library. CMake is use to generate makefiles.
But when I run 'make' it takes around a minute or more to compile the application (the final
executable is around 6 MB) on Ubuntu 9.10 on a 3 GHz Intel Core 2 Duo 8400 CPU and 6 GB RAM.
When I compile the same program (using the same CMakeFile) in windows vista using Visual Studio 2008
it takes under � the time (approx 20 sec.).
Any ideas why its faster to compile on windows (do the visual studio compiler use some optimizati...Time change in Linux OS
Time set on Linux system has changed slightly day by day.
I heard it's a linux bug. And to overcome this troublem I should bring
other computer's(server's) time and set time with them. But i don't
use my computer on a network system. so I need other way to fix this.
If this is the problem of OS, may I use C-mos time? (but i donno how
yet.. --;) More over Plz let me know the reason for this.

Xubuntu, but Ubuntu in general 'cause it's the tidal surge of Linux

I've found a problem happening on a load of linux servers I run.
Basically the clock is slowing right down so much that the clock changing
a second takes a minute or more. If I try to run top nothing happens, so I
assume the CPUs are being used insanely.
I forgot to check hwclock before rebooting, but as the clock is ok after
reboot (it was about 4 days out before reboot) so I assume it's ok.
Anybody have a clue as to what might be causing this? And where I could
look to find clues? I'm guessing it's a program not playing nice with the
hardware. I am steering away from hardw...Why are OS X and linux so darn slow?

Same situation with Linux (kubuntu), just not as snappy as XP.

So, not that many of you would care, but this month I have a rather
odd anniversary: it was 10 years ago that I laid eyes on my first
Linux ditribution, and it was the thing that "started it all" for
me. I was in the 9th grade, still using Windows, but I had access to
a Redhat box, and I loved it. I remember playing Sokoban a lot on
it, and I seem to remember Netscape. I also remember BitchX, but
that was years after.

On my win32 machine I have following info in my outlook setting:
smtp server: smtp.xxx.com, email name email@example.com
My outgoing server (SMTP) requires authentication checked
Log on using checked
User Name: sss, password: ttt
I want to be able to send out email from my new installed laptop(redhat
linux 7) so I tried modifying the /etc/mail/sendmail.mc by adding
and then I do
mc sendmail.mc /etc/sendmail.cf
it compiles ok, but after I reboot the sendmail daemon. It doesn't work.
If I send an email(I am using mail) to firstname.lastname@example.org, then verizon.net
told me that I am not authorized, if I send email to some email@example.com then
it told me that I am in black list which I swear I have no idea about.
I know senmail is a mail server and should be much more powerfull than
the outlook stuff. But the setup of sendmail really frustrate me. I don't
need a mail server, I just want be able to send out my email (I don't even
need receive any email from outside) Can the sendmail do that and if it can
how should I set it up?
Also I want everyone who can use my laptop (with different account) can
use the same setting, is that possible?

...first-time linux server setup: general questions
I'm currently system administrator in a small company (5 clients and one
We decided to buy a new server since the old ran windows nt 4 and
doesn't suit our needs anymore.
the idea came up to run a linux server. I have some Red Hat 9
experience, but not too much and not as server either. Actually, the
server is only a file & print-server for the clients, so the following
things should be possible:
Using the usb-printers Canon BJC S9000 und 900 flawlessly for the
windows clients, as well as the Toshiba TEC B-440 printer. This is
crucial: It's an old label printer, it's using the serial port.
The server has a connected HP SureStore DLT40 tape which should run a
nightly backup. It should also serve a logon script which automatically
connects the domain clients to the mapped network drives and exectues
some other commands.
I'd be very interested in a client/server anti-virus solution, which
means that the server downloads the definitions and delivers them to the
windows (98) clients. It should be able to kill infected windows files
on the ext3 partition as well.
Ths server should be able to receive vpn dial-ins.
Generally, the windows users should not see any difference compared to
the old server.
Is this a possible setup for a linux beginner, yet windows specialist
within a reasonable time? I'd be very happy if you could tell me what

The linux box (SuSe Linux 8) mounts an NFS export on the OS X machine.
When I copy files from the linux machine to OSX, the speed is fine.
But copying files from the OSX system to linux is very, very slow. I
